Abstract

To prolong the life of press felt which in the paper and cardboard industry is used in conjunction with press rollers to remove water from a paper web from which some of the water has already been removed by means of screening and vacuum, enzymes are sprayed into and onto the press felt to remove water binders and water bound thereto. After a pecific period of action of the enzymes, the latter are rinsed out.
